So is your compression still 10:1¿

Oh just looked at your sig. So high comp turbos arent very common are they.

13.5:1. No. Common turbo builds are usually 9:1. In 2012 the standard shifted more towards 10:1 but its rare to see 11:1 or higher.

If you feel like answering this: Why high comp turbo? What has to be different from most turbo builds on high comp?

I was bored with the standard builds – Low compression with an oversized turbo. I wanted to try something radically different and challenge some common myths about compression and boost. Not much is different on a high comp build aside from the pistons. The fuel is critical - None of this would be possible without Ethanol.
